Locate a hidden beacon on the 11 × 11 floor. Move your listener, spend up to 8 listens, then place one guess within 1.5 tiles. Right-ear emphasis means the source is to your right; louder means nearer. Move vertically to resolve front/back ambiguity.
Headphones help. Start quietly. Visual cue mode provides equivalent pan and distance evidence without sound; assisted rounds are labeled.
